THOMAS KEN EDY, or BIRMINGHAM, ENGLAND.

LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 241,670, dated May 1'7,1881.

I Application filed October 22, 1880. (No model.) Patented in EnglandJune 4, 1880.

To all whom it may concern:

Be it known that I, THOMAS KENNEDY, of Birmingham, England, haveinvented certain new and useful Improvements in Lamp-Burners; and Ihereby declare the same tobefnlly, clearly, and exactlyrdescribed asfollows, reference being had to the accompanying drawings, in which-Figure l is a central vertical sectional view of the burner as attachedto the lamp-body. Fig. 2 represents, in side elevation, certainmodifications of the collar which receives the burner and is permanentlyattached to the lamp; and Fig. 3 is a plan and horizontal section of thesame, as hereinafter explained.

My invention relates to lamps for burning volatile hydrocarbons; and itconsists in certain features of construction of the burner and itscollar, designed to facilitate the attachment and removal of the burner,when desired, as well as to cheapen and simplify the construction ofthese parts.

Heretofore the oil-reservoir has generally been furnished with a collar,threaded on the inside and attached to the fount or oil-reservoir bymeans of plaster or gypsum, the burner being screwed into the collar. 1obviate in great measure the expense of thismode of construction, andthe trouble attending the connection of the parts, by forming the collarand burner as follows:

B is the fount, having the collar 13 formed integral therewith bycasting if of glass, or spinning if of metal, or otherwise suitablyattached thereto. The collar is furnished with two or more inclinedbeadsor projections, a, above which is a plain cylindrical portion, 1,designed to facilitate the attachment of the burner.

The burner A has the usual wick-tnbe a, and its lower portion is spun upfrom a sheet-metal tube bycompressingit upon a mandrel by dies orrollers.

1t terminates below in a collar or neck, A, large enough to pass overthe collar B, and in it are formed indentations b b, so located as tocome opposite the projections c. A washer, G, of leather or suitablematerial is interposed between the top of the collar and the neck A, asshown To connect the parts the burner is simply brought down over thecollar, the indentations b being made to come opposite the spacesbetween the projections c. The burner is then turned partly round,causing the indentations to come under the projections and draw theburner closely down upon the washer. The elasticity of the latter willgenerallysuffice to prevent the accidental reverse rotation of theburner with reference to the collar; but for greater security Iprefer toprovide against such a contingency by corrugating the under side of thehead, as shown at c, Fig. 2, or by formin g a series of verticalgrooves, c, beneath the bead, a spring-catch, thumb-screw, or otherdevice being attached to the burner to engage therewith.

It will thus be seen that the described construction of parts admits ofthe collar and burner being most conveniently struck up or spun, andtheir attachment and disconnection are greatly facilitated.

Obviously, the relative positions of the indentations and projectionsmay be reversed that is to say, the former may be made upon the collarand the latter on the burner.

I am aware that collars have been joined to the necks of lamp-founts bybayonet-joints, and that inclines have been formed on the necks ofpreserve-jars, with which lugs on the ends of the cover-bail engaged,the principle in each case being the same; but such I do not claim.

What I claim is In combination with the collar B, integral with orsecured to the fount, and having one or more inclined heads, 0, andcylindrical portion 1, and corrugations or indentations, as described,the burner having indented cylindrical portion A and washer 0, all asset forth.

In testimony that I claim the foregoing as my own I affix my signaturein the presence of two witnesses.

THOS. KENNEDY.
